Description

TECHNICAL FIELD

[0001] The specification relates to the field of Internet technologies, and in particular, to a dynamic graphic code implementation method and apparatus.

TECHNICAL BACKGROUND

[0002] A graphic code such as a bar code or a QR code is an information carrier, and is a graphic identifier generated by processing, such as coding, information according to a certain rule.

[0003] To ensure that private information carried in the graphic code is not stolen, it is necessary to provide a more reliable and secure graphic code implementation scheme.

SUMMARY OF INVENTION

[0004] In view of the above, the specification provides a dynamic graphic code implementation method and apparatus.

[0005] Specifically, the specification is achieved by the following technical solutions:

invoking a distance sensor to detect a distance between a device and a blocking object when displaying a graphic code; and

if the distance is within a set distance range, stopping refreshing the graphic code.

[0006] A dynamic graphic code implementation apparatus, comprising:

a distance detecting unit configured to invoke a distance sensor to detect a distance between a device and a blocking object when displaying a graphic code; and

a refresh stopping unit configured to stop refreshing the graphic code if the distance is within a set distance range.

[0007] A dynamic graphic code implementation apparatus, comprising:

a processor; and

a memory configured to store a machine executable instruction;

wherein by reading and executing the machine executable instruction stored in the memory corresponding to a dynamic graphic code implementation control logic, the processor is caused to:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0010] Example embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. If the drawings are involved in the following description, the same numeral in different drawings refers to the same or similar elements, unless otherwise indicated. The implementations described in the following example embodiments do not represent all implementations consistent with the specification. Instead, the implementations are merely examples of apparatuses and methods consistent with what are described in detail in the appended claims and some aspects of the specification.

[0011] The terms used in the specification are merely intended to describe particular embodiments, and are not intended to limit the specification. The singular forms "a" and "the" used in the specification and the appended claims are also intended to include plural forms, unless other meanings are clearly indicated in the context. It should also be understood that the term "and/or" as used herein refers to and encompasses any or all possible combinations of one or more associated listed items.

[0012] It should be understood that although the terms, first, second, third, etc. may be used in the specification to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, the first information may also be referred to as the second information without departing from the scope of the specification. Similarly, the second information may also be referred to as the first information. Depending on the context, the word "if' as used herein may be interpreted as "at the time of' or "when" or "in response to determination."

[0013] In this embodiment, in addition to the specified information, a dynamic graphic code generally carries a time factor, such as a timestamp of the time when the dynamic graphic code is generated. A graphic code generating device can generate graphic codes carrying different time factors for the specified information with the change of time, and a graphic code analyzing device can determine whether the graphic code is reliable according to the time factor, thereby improving the security of the graphic code and reducing the risk of information leakage.

[0014] FIG. 1 is a schematic diagram showing a dynamic graphic code implementation process according to an example embodiment of the specification.

[0015] Referring to FIG. 1, the specification provides a dynamic graphic code implementation method, which can be applied to a client that displays a graphic code. The client is generally installed in an electronic device such as a mobile phone or a tablet computer. The dynamic graphic code implementation method can include the following steps:
Step 102: a distance sensor is invoked to detect the distance between a device and a blocking object when a graphic code is displayed.

[0016] In this embodiment, the display of the graphic code can be triggered by a user. For example, in offline electronic payment, the user opens a payment graphic code, and in riding a bus, the user opens a riding graphic code. The payment graphic code and the riding graphic code are generally dynamic graphic codes, which can be updated over time. In this embodiment, the distance sensor of the device can be invoked to detect the distance between the device and the blocking object when the graphic code is displayed. For example, the device is a mobile phone, and the distance sensor is generally located in the vicinity of a phone receiver. The positions of distance sensors of different devices may also be different, and details will not be described in this embodiment.

[0017] In this embodiment, after the graphic code is displayed, a code scanning operation is generally performed, and the blocking object is generally a code scanning device, such as a barcode scanner and a terminal device having a code scanning function. Certainly, the blocking object may also be other objects, such as a user's finger or other objects, and is not particularly limited in this embodiment.

[0018] Step 104: If the distance is within a set distance range, refreshing the graphic code is stopped.

[0019] Based on step 102, when the graphic code is displayed, if it is detected that the distance between the device and the blocking object is within the set distance range, it is indicated that the probability that the code scanning operation is currently being performed is high, and the refreshing of the graphic code can be stopped, so as to avoid the security risk caused by the refreshing of the graphic code in the code scanning process, for example, the code scanning device scans two graphic codes before and after refreshing, and then two payment requests are initiated.

[0020] The distance range is generally a range of distance from the device when the code scanning device can successfully scan the graphic code, which can be preset by a developer, for example, 0 cm-5 cm, and 0 cm-10 cm, etc.

[0021] In this embodiment, in a client refresh mode, stopping refreshing the graphic code may include: not generating a new graphic code when the refresh time of the graphic code arrives. The client refresh mode refers to the generation of graphic code by a client.

[0022] For example, the graphic code is a payment QR code, it is assumed that the refresh period of the payment QR code is 1 minute, the blocking object is a code scanning device. After the payment QR code is displayed, if the refresh mode is the client refresh mode, the client can generate a new payment QR code according to the user's account information and time factor every minute, and refresh the currently displayed payment QR code with the newly generated payment QR code. It is also assumed that the client displays the payment QR code at 16:22:02, the next refresh time of the payment QR code is 16:23:02. If it is detected at 16:22:58 that the distance between the mobile phone and the code scanning device is within the set distance range, the client does not generate a new payment QR code at 16:23:02.

[0023] In this embodiment, in a server refresh mode, stopping refreshing the graphic code may include: not sending a refresh request to the server when the refresh time of the graphic code arrives. The server refresh mode refers to the generation of graphic code by the server. For example, when the graphic code is displayed or refreshed, the client sends a request to the server, and the server generates a graphic code and then sends it to the client.

[0024] For example, the graphic code is a payment QR code, the refresh period of the payment QR code is 1 minute, and the blocking object is a code scanning device. After the payment QR code is displayed, if the refresh mode is the server refresh mode, the client can send a refresh request to the server every minute, and the server generates a new payment QR code according to the user's account information and the time factor, and sends the newly generated QR code to the client for the client to refresh. It is also assumed that the client displays the payment QR code at 16:22:02, the next refresh time of the payment QR code is 16:23:02. If it is detected at 16:22:58 that the distance between the mobile phone and the code scanning device is within the set distance range, the client does not send a refresh request to the server at 16:23:02.

[0025] As can be seen from the above description, this embodiment can invoke a distance sensor to detect the distance between a device and a blocking object when displaying a graphic code, and stop refreshing the graphic code if the distance is within a set distance range, which avoids the security risk caused by the case that the code scanning device scans two graphic codes before and after refreshing, thereby improving the reliability and security of the dynamic graphic code.

[0026] Based on the embodiment as shown in FIG. 1, the refreshing of the graphic code can be restored if it is detected that the distance between the device and the blocking object is not within the distance range after stopping refreshing the graphic code.

[0027] For example, the graphic code is a payment QR code, the refresh period of the payment QR code is 1 minute, and the blocking object is a code scanning device. It is assumed that the set distance range is 0 cm-5 cm, and the client displays the payment QR code at 16:22:02. If it is detected at 16:22:58 that the distance between the mobile phone and the code scanning device is 4.5 cm, the refreshing of the payment QR code can be stopped, for example, at the next refresh time 16:23:02, the client does not generate a new payment QR code. It is also assumed that at 16:23:15, the distance between the mobile phone and the code scanning device is detected to be 15 cm, which is not within the distance range. If the payment QR code is still displayed at the moment, the refresh of the payment QR code can be restored.

[0028] In an example, the implementation for restoring the refreshing of the payment QR code may be: refreshing the payment QR code when it is detected that the distance between the mobile phone and the code scanning device is not within the distance range, for example, a new payment QR code is generated according to the current timestamp and the user account for refreshing. Still taking the above example as an example, the payment QR code can be refreshed at 16:23:15. After the payment QR code is refreshed, the next refresh time can be based on the time 16:22:02 when the payment QR code is displayed, for example, 16:24:02, or based on the refresh time 16:23:15 after the restoring, for example, 16:24:15, which is not particularly limited in this embodiment.

[0029] In another example, the implementation for restoring the refresh of the payment QR code may also be: refreshing the payment QR code when the next refresh time arrives. Still taking the above example as an example, at 16:23:15, the distance between the mobile phone and the code scanning device is detected to be 15 cm, and the refreshing of the payment QR code can be made at the next refresh time 16:24:02 of the payment QR code.

[0030] Certainly, the refreshing of the payment QR code can be restored in other ways, which is not particularly limited in this embodiment.

[0031] Based on the embodiment as shown in FIG. 1, after the refreshing of the graphic code is stopped, the refreshing of the graphic code can be restored when a time duration since the refreshing the graphic code is stopped reaches a set time duration. The set time duration is generally a time duration required for successful scanning, and can also be set by a developer, such as 5 s and 10 s.

[0032] For example, the graphic code is a payment QR code, the refresh period of the payment QR code is 1 minute, and the blocking object is a code scanning device. It is assumed that the time duration since the refreshing is stopped is 10 s, and the client displays the payment QR code at 16:22:02. If the refreshing of the payment QR code is stopped at 16:22:58, the refreshing of the payment QR code can be restored at 16:23:08. For the implementation for restoring the refreshing of the payment QR code, reference can be made to the foregoing description, and details are not described in this embodiment again.
